    Any other parquet dependencies? If they are not needed, why the explicit dependency on
org.apache.parquet:parquet-column is necessary?

> Currently Drill uses [Hive version 1.2.1 libraries|https://github.com/apache/drill/blob/master/pom.xml#L53]
to perform queries on Hive. This version of library can be used for Hive1.x versions and Hive2.x
versions too, but some features of Hive2.x are broken (for example using of ORC transactional
tables). To fix that it will be good to update drill-hive library version to 2.1 or newer.

> Tasks which should be done:
> - resolving dependency conflicts;
> - investigating backward compatibility of newer drill-hive library with older Hive versions
(1.x);
> - updating drill-hive version for [MapR|https://github.com/apache/drill/blob/master/pom.xml#L1777]
profile too.
